The one DNA sample we have is only the regular Male DNA......not the extensive 23 and Me test.......which tells you what percentage you are of Native, African etc.....

We would need to have that done in order to prove that Mathilda brought native DNA into the family........

but there is no Charles Sears and no marriage to a Charles Sears: all the evidence says that never happened.........she was barely 17 when she married Witt....and prior to that she was in southern Missouri living with her parents......and no Sears lived in that region at all......

If Lewis carried some version of a known Sears DNA sample it would help: but in fact he does not: he carries the DNA of a very well known Tuscumbria family......not Witt

There is a marriage license for Witt though: no one knows what became of him.
